FM Signal Internal Disconnect

[FLT DOC]

What would cause the signal input from a FM antenna to a FM tuner to electronically "disconnect" after a few minutes? All physical connections are good but after about 10 minutes the signal "drops" and I'm left with only static. It's a reliable but old T-17 Yamaha. Fixable?

Does the signal come back after you re-tune it? Is the unit cold when it starts working, then after 10 min of warmup it dies, or is it already warmed up?

T-17

Thanks for reply.

Mostly the unit is at room temp when I turn it on. After about 10 min there is a "crackling" sound in the speakers as if the connection was being physically moved. Then continuous static. Trying later, after about an hour, I can get a signal again.
